Microscopes

Question 1

This is easy you stupid shit: What can you see with an electron microscope that you cannot see with a traditional light microscope?

Answer 1

Bacteria, Viruses, molecules, atoms in crystals.

Question 1

Alright dumb fuck: Why are photons not suitable for viewing objects smaller than atoms?

Answer 1

Photons are too large and have wavelengths that are not short enough to resolve objects smaller than atoms.

Question 2

Alright stupid ass motherfucker: What replaces photons in an electron microscope to enable higher resolution imaging?

Answer 2

Electrons, which have a much shorter equivalent wavelength.

Question 3

Alright Mr. get-no-bitches, How do Electron Microscopes Work
What are the four main components of an ordinary microscope, and what are their equivalents in an electron microscope?

Answer 3

Light source (replaced by electron beam), specimen (needs vacuum), lenses (replaced by electromagnets), and the image (electron micrograph or screen image).

Question 4

Since you can’t pull at all, How do electron microscopes achieve magnification?

Answer 4

By bending electron beams with electromagnets instead of using lenses to bend light.

Question 5

You stupid fuck you need an electron microscope for that shrimp size brain of urs: Types of Electron Microscopes
What distinguishes a Transmission Electron Microscope (TEM) from a Scanning Electron Microscope (SEM)?

Answer 5

TEMs image the insides of materials by transmitting electrons through them, while SEMs image surfaces by scanning them with electrons.

Question 6

Bitch, listen: How does a Scanning Tunneling Microscope (STM) differ from TEMs and SEMs in terms of functionality and specimen damage?

Answer 6

STMs use a sharp metallic probe to scan surfaces at atomic levels without high-energy electron beams, reducing specimen damage.

Question 7

Lazy ass mf
Define ‘micrograph’.

Answer 7

A photo taken through a microscope.

Question 8

You stupid mf: What does magnification mean in microscopy, and how is it different from resolution?

Answer 8

Magnification is enlarging the image of an object, while resolution is the ability to distinguish between two closely situated objects.

Question 9

Dumb little shit: How is contrast enhanced in microscopy?

Answer 9

By using stains or fluorescent substances to distinguish structures against the background.
